Prepare to Use Extensions¶
If you are running a package installation of CKAN, before you start using and testing extensions (described in Add Extensions) you need to prepare your system.
Firstly, you’ll need to set up and enter a virtual Python environment, as follows:
sudo apt-get install virtualenv python-pip mercurial virtualenv /home/ubuntu/pyenv . /home/ubuntu/pyenv/bin/activate
Then, you need to install the CKAN source into your virtual environment. You can install CKAN like this:
pip install -e hg+http://bitbucket.org/okfn/ckan#egg=ckan
Your new CKAN developer install will be running on http://localhost:5000/
When you start using extensions, you should install any of the developer versions of the CKAN extensions you want to work on like this (using the appropriate URL):
pip install -e hg+http://bitbucket.org/okfn/<dependency-name>@<version>#egg=<egg-name>
The dependency you’ve installed will appear in /home/ubuntu/pyenv/src/ where you can work on it.
After working on extensions, you should make sure that your deployment passes the tests, as described in Testing for Developers.
